Given an array of attributes, returns a string in the serialized attributes format prepared for post content.
Description
The serialized result is a JSON-encoded string, with unicode escape sequence substitution for characters which might otherwise interfere with embedding the result in an HTML comment.
This function must produce output that remains in sync with the output of the serializeAttributes JavaScript function in the block editor in order to ensure consistent operation between PHP and JavaScript.
Parameters
$block_attributesarrayrequired- Attributes object.
Source
// If the rendered content was previously empty, we leave it like that.
if ( empty( $response->data['content']['rendered'] ) ) {
return $response;
}
// `apply_block_hooks_to_content` is called above. Ensure it is not called again as a filter.
$priority = has_filter( 'the_content', 'apply_block_hooks_to_content_from_post_object' );
if ( false !== $priority ) {
remove_filter( 'the_content', 'apply_block_hooks_to_content_from_post_object', $priority );
}
